Not launch-quality. It is graded C with a clean safety verdict, but our quality filters exclude it: a model that read it found it written only for the repository it lives in. So it is not in our launch-quality set, the skills our MCP server searches and recommends. How launch-quality is decided

Documents its own correctness edge case — extra matching log lines can silently shift which samples get counted — a self-aware caveat rarely seen in a measurement tool's own docs.
